Looks like -mnobitfield option increases object's size more than 100%. I don't
know if so big file size increase is correct. Another problem can be noticed
with GCC 4.4.2 which generated 45% bigger object than the rest

GCC 4.5.0 (20091224): 840KB
When I use -O3 -fno-inline-functions -fno-unswitch-loops
-fno-predictive-commoning -fno-gcse-after-reload -fno-tree-vectorize, size
increases to 944KB.

The problematic function is as was said ff_rate_estimate_qscale.
I found out which optimizations causes the problem:
-m68020 -m68881 -O1 -fno-tree-ccp -fno-tree-dominator-opts (works ok).
-m68020 -m68881 -O1 (Abort trap

m68k-amigaos is not a supported target.
LOL! So you prefere to not get any bugreports? I reported a few bugs which were
next confirmed on the other hardware and after some time fixed, no matter if I
use unsupported m68

No, asm code looks the same like with -O2 option:
_flv_probe:
clr.l d0
rts
.even
Here are GCC's options which I used (should be included in the first post):
$ make_68k_v45

-O2 -fno-cse-follow-jumps (works OK):
_flv_probe:

Works for me with 4.5.0 20091228.
How's that possible? What about GCC 4.4 branch? I just checked with ATARI GCC
4.4.2 m68k compiler and got the same result:
/usr/local/cross-mint/bin/m68k-atari-mint-gcc -c -S flvdec_O2.i

This slowdown is because of libz. When I use minigzip from libz package to
compress data, I get the same slowdown with GCC 4.4.1. Maybe someone will try
to fix it?
